PP Melt Blown Fabric Making Machine Quality After-sales Service
1. Application of PP Melt Blown Fabric Making Machine
(1) Melt blown cloth is the core material of masks. Medical masks and N95 masks are composed of three layers, namely spunbond layer, meltblown layer and spunbond layer. The spunbond layer and meltblown layer are made of polypropylene PP Melt Blown Fabric Making Machine, but the production process is different. The production machines used are also different. GWELL company mainly manufactures the melt blown cloth production equipment.
(2) Other applications of meltblown cloth: medical and health cloths, such as surgical gowns, protective clothing, disinfection wraps, masks, diapers, sanitary napkins, etc. Industrial cloths, such as filter materials, insulating materials, industrial wipes, cement packaging bags, geotextiles, covering cloths, etc.PP Melt Blown Fabric Making Machine
2. Process of PP Melt Blown Fabric Making Machine
Prepare the raw materials, then feed the raw materials into the extruder for melting. The melt material goes through the screen changer and metering. The melt is sprayed from the spinneret to the forming belt to form as the melt blown cloth. The melt blown cloth is processed by the electrical electret treatment device, and then cut and wound.
3. Advantages of PP Melt Blown Fabric Making Machine
(1) Adopt special coat hanger type and gas equalizing type spinning die with independent intellectual property rights, and the melt distribution is even.PP Melt Blown Fabric Making Machine
(2) The air nozzle has stable air pressure, symmetrical air flow on both sides, and uniform air flow in the width direction.
(3) It is convenient to adjust the width of the air gap.
(4) It adopts a specially designed hot air heating device, which has very good heating efficiency and excellent heat exchange efficiency, and low energy consumption.PP Melt Blown Fabric Making Machine
(5) The receiving distance is adjustable, and the receiving form is flat network receiving, which is convenient for maintenance.
Gwell plastic transparent sheet unit production line absorbs and digest western country advanced extrusion technology. And its main parts choose from all over the world (such as screw, barrel, roller, etc.). The energy consumption of its complete sets of equipment , intelligent, automation, safety standard, technology standard, etc., have been at or near the world standard of the product.

The raw material of the mask is polypropylene PP Melt Blown Fabric
Making Machine. The medical surgical mask is generally multi-layer
structure, commonly referred to as SMS structure, as shown in
Figure 1 and Figure 2.
The S in the mask layer stands for spunbonded fiber, with a coarse
fiber diameter of about 20 microns (nm). The two layers of
spunbonded fiber mainly support the whole non-woven fabric
structure, and have no obvious effect on the barrier performance.
The most important layer inside the mask is the barrier layer or
melt-blown layer (M). The fibers in the meltblown layer are
relatively thin, about 2 microns (M) in diameter, and thus only
one-tenth the diameter of the spunbond layer, which is essential to
keep bacteria and blood out of the layer.PP Melt Blown Fabric

The fibers of the spun adhesive layer, the meltblown layer, and the shape of the hair are compared. As shown in the figure, 1/3 of the diameter of the hair is close to the fibers of the spun adhesive layer, and 1/3 of the diameter of the hair is close to the fibers of the meltblown layer
